SHELL-ROLLS FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 709,298, dated September 16, 1902.

Application filed March Z0. 1902.

Be it known that I, ARTHUR G. BoozER, a citizen of the United States, residing at Tucapau, in the county of Spartanburg and State of South Carolina, have invented new and useful Improvements in Shell-Rolls for Spinning-Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in shell-rolls for spinning-machines, the object being to improve the construction thereof, provide AVantit'r'iction bearing devices, means whereby the shell-rolls will be self-adjusting to and from the lower rolls, and means for lubricating the bearings; and with the above ends in view the invention consistsin the construction and combination of the parts, as will be hereinafter set forth.

In the accompanying drawings, which illustrate one` practical embodiment of my invention, Figure l is an end View showing a saddle upon the top rolls and a stirrup which engages the saddle, the saddles and stirrup being shown in dotted lines. Fig. 2 is a front elevation of a shell-roll, showing one roll out of a horizontal line with its spindle. Fig. 3 is a sectional View, the section being taken through different parts. Fig. 4 is a partA plan and part section, the shells and outer sleeves being removed. Fig. 5 is a section on the dotted line 3 3, and Fig. 6 is a sectional view of a modication in which balls are used instead of rollers.

Referring to the drawings, l indicates the main arbor or bearing, upon which the sad? dles shown in dotted lines bear, the requisite degree of pressure being appliedv to the rolls by a Weight connected to the stirrup. The arbor or main bearing l has end iianges, and` from its central portion to project laterally are hollow spindles 2 2, the ends thereof being closed by plugs 3 3. The openings through the spindlesconnect with an opening through the arbor, which is internally threaded to receive one endof a tube 4-.. The tubes 4, carried by the arbors, pass :into or through openings in the saddles to hold the rolls in place and at the same time provide oil-passages for conveying lubricant to the bearings of the rolls. Upon the spindles aresecured sleeves ameter of the spindles.

Serial No. 99,186. (No model.)

5 5, the ends nearest the arbor 2 having flanges and the internal diameter of these sleeves is much greater than the external di- The sleeves and spindles are movably connected by hollow trunnions 7 7, disposed at substantially right angles with the tubes 4, the sleeve being susceptible of a rocking movement on the spindle, so that the roll may adapt itself to inequalities either as to the size of the top roll, the bottom one, or variations in the size of the yarn. By providing hollow trunnions, the openings being in line with each other to provide oil-passages, the openings may be readily cleared of obstructions. The trunnions connect the sleeves to the spindle so that such sleeves may have an oscillatory movement, the fulcrums being at the center of the spindles, and said sleeves provide raceways for rolls which are arranged in circular series, the flanges forming bearings for the inner ends thereof, the outer ends of the sleeves being threaded for the reception of nuts S 8. The outer sleeve 9, which revolves on the rollers 10, has an annular inwardlyextending flange against which the inner nut will abut, the outer nut serving to lock the inner one in place, and these nuts are of less Vdiameter than the internal diameter of the shells ll, which tightly embrace and turn with the outer sleeves 9. The shells are covered in the usual manner and are of sufficient length to extend over the nuts. To lubricate the bearings of the rolls, oil is fed through the tubes 4, from thence iiows into the hollow spindles, and passes as required through the hollow trunnions to the raceways of the rolls, and owing to the construction there is but little liability, if any, of the oil coming in contact with the faces of the rolls or the yarn.

The construction shown by Fig. 6 admits of balls being used instead of rollers, and when such construction is desired the ends of the outeg sleeve are beveled and balls of the requisite size are used, such balls having their bearings against the end of the sleeve, they being retained at one end by the Iiange 6 and at the other end by the inner nut 8. The lubricant passes to the raceways through the hollow trunnion 7. The nuts, which are cir- IOO ' an oil-duct through the arbor which commu- `sleeves rotatively mounted on the inner cular, are provided with notches or recesses, l so that they may be removed by a suitable wrench.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In shell-rolls for spinning-machines, the combination of a hollow arbor and spindles,

nicates with the chamber within the spindles, sleeves of larger interior diameter than the exterior diameter of the spindles, hollow trunnions which connect the inner sleeves to the spindles and at the same time provide oilpassages between the chamber in the spindles and the exterior of the inner sleeves, outer sleeves, and antifrictionrolls between the shells, substantially as shown.

2. In top rolls for spinning-machines, the combination of non-rotative spindles, an inner shell pivoted thereto and capable of an oscillatory movement on the spindle, a nut carried by the outer end of the inner sleeve, an outer sleeve rotatively mounted on the inner sleeve and held against longitudinal move-` ment in one direction by the nut, and antifriction-rolls between the shells, substantially as shown.

` 3. In shell-rolls for spinning-machines, the combination of a hollow arbor and spindles constructed to provide an oil-duct between the arbor and the spindles, an inner shell with' flanges adjacent to the arbor and screwthreads near their outer ends, hollow trunnions pivotally connecting the inner shells to the spindles and providing oil-passages from the hollow spindles to the outer faces of the inner shells, nuts on the screw-threaded ends of the inner shells, antifriction-rolls between the shells and also between the danges and nuts on the inner shells, and a shell-roll of suicient length to cover the outer shell and thelnuts, substantially as shown.

4. The combination with a non-rotative spindle, an inner shell of greater internal diame'ter than the external diameter of the spindle, hollow trunnions between the spindle and innershell, an outer shell rotatively mounted on the inner oscillatory shell, a shell-roll carried by the outer rotary shell, and means removably connected to the non-rotative shell to hold the outer shell against longitudinal movement thereon, substantially as shown.

lIn testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
